Bad Nedbank to drop a 86yr old

Assisting a 86 year old lady trying to find out why the amounts on 32 days and 6 months differs and no one replies from Nedbank side. We even gave them all her co tact details and she gave in the mail permission that they can even call me or email me. She 1st contacted Nedbank and visited them November 2023. No one could assist her and she was told the manager is ill. She had certain amounts on investment and when it matured and had to be reinvested the amount was suddenly R46 000 less. She never once used any of the funds invested.14 November she contacted Nedbank on *** and the Wayne she spoke to could not answer her about this issue. The above was sent to feedback at Nedbank and no reply on the mail. She again called Nedbank because no response on email. 26 December 2023 again another email to the bank and again put down contact details and I'd number and investment number/client number trying to resolve this. No response on email. The client who is 86 end up again calling and talked to Olivia Mike. This lady gave her a ref number ***1 and even picked up an investment that is on 32 days since 2019. So she lost all these years interest on it as 32 days is far less interest than a 6 months fixed deposit. Amount was given R69 251.24. In the mail we asked how the monies must be invested and the client want statements when it has been done. Until today no email or even a call tot her Mrs Laufs. 05 Jan 2024 another mail to nebank asking to please respond. Until now....no response. So this 86 year old lady does not know what is going on with her money nor investments at nedbank and she wants a solution very quick as this has dragged feet since November 2023.
